Status of Factorization Efforts, 9,000 < n < 10,000

N.Daminelli has completed 990 runs of gmp-ecm with B1=1M for the Aurifeuillan composites in this range.

Each composite number with less than 436 decimal digits in this range has been tested by N.Daminelli with 990 runs of gmp-ecm with B1=1M.

Each composite number in this range has been tested by A.Kruppa with the gmp-ecm implementation of the Pollard p-1 algorithm with B1=1M and B2=100M.

Each composite number with less than 800 decimal digits in this range has been tested by A.Kruppa with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=1G and B2=1T.

Each composite number with less than 1200 decimal digits in this range has been tested by H.Bock with the gmp-ecm implementation of Pollard's p-1 algorithm with B1=100M and B2=100G.

Each composite number in this range has been tested with the p+1 algorithm with B1=100000 B2=2781811, starting points randomly chosen by A.Kruppa.

Each composite number in this range has been tested by N.Daminelli with the gmp-ecm implementation of the p+1 algorithm with B1=6M and B2=93G.
